My invention relates to spectacles. The object of my invention is toprovide sup- 1 porting means for eye glass lenses whereby the lenseswill be less liable to injury by reason of stresses set up in the frameparts in the act of handling the spectacles. I

A further object is to provide means for preventing glasses of the typethat are supported on the nose by means of a spring nose-piece only,from becoming displaced by reason of the weakness of the spring.

A further object is to provide spectacles with bows which are readilyattached to and removable from the nose piece of the frame in which 15the glasses are mounted, without the use of screws.

A further object to provide supporting means for glasses which extendover or above the top edges of the glasses to protect them, and whichalso provides bows or supporting side parts which are located above theplane of the normal line of vision of the wearer, and also to providemeans,

whereby the side parts will exert a clasping pressure on the sides ofthe head to firmly support the glasses, regardless of the usual loopform of the ends commonly in, use.

Further objects of my invention and the utility of same will behereinafter more clearly set forth.

'0 Referring to the drawing which forms a part of these specifications:

Fig. 1 is an elevational illustrative view of a pair of glasses held inproper position by a spring nose-piece, with my attachment mounted athereon.

Fig. 2 is a'plan view of the cross-piece, with the separable bows orside-clips attached thereto;

.Fig. 3 is a cross sectional view of line 3-3 of Figure 1.

Fig. 4 is a plan view on line 4-4 of Figure 1, showing one form of jointbetween the crosspiece and side-clips.

Fig. 5 is a plan view showing the clip asit appears in the act ofattaching or detaching the 5 clip from the cross-piece.

Fig. 6 is a cross sectional view thru the crosspiece and spring of thenose-piece, showing the construction used when the cross-piece isattached to the spring in separable relation.

50 Fig. 7 is a front view of another form of separable jointconstruction in which the end of the clip slides into a pocketformed-onthe end of the cross-piece.

Fig. 8 is a cross sectional view on line 8-4 of 68 Figure'l.

Fig.9 is a plan view of the construction shown in Figure 7.

Fig. 10 is a plan sectional view showing a shoulder abutment formedintegral with the cross-piece and also a loop formed in the end of thecross-piece to provide more flexible spring action. a

Fig. 11 is a plan view, partly in section, of a modified form ofconstruction in which the end of the side clip is provided witha holeinto which 1 a detent enters when the end of the clip is forced thru aslot formed in the end of the cross-piers to its normal position, thebent over portion of the cross-piece acting as a spring due to thresiliency of the metal. a

Fig. 12 is a plan sectional view of a detachable joint in which arelatively long abutment is formed on the cross-piece and is stiffenedby the fold of the metal.

Fig. 13 is a plan view, partly in section, of a- 20 joint and anabutment, and a hinge having a per end of a nose-piece with thecross-piece con nected at two spaced points therewith, and bowed so thatthe action of the spring will not be stiflened, etc.

Fig. 15 shows a' construction in which the nosepiece and frame for thelenses are made of plastic material, and the top of the nose-piece isformed to receive a cross-piece which extends in curved form over thelens. 35

Fig. 16 is a view showing a plastic side clip in engagement with across-piece in separable relation.

20 indicates a pair of glasses of the usual form and construction ingeneral use and in which a o nose piece comprising a spring 2| is usedto support the glasses.

:2 indicates a cross-piece'made oi resilient metal or other suitablematerial.

When made of metal, the cross-piece is prefa erably made of 'a thinstrip to permit flexing in a limited degree to and from the top edges ofthe glasses, but'wide enough. to be rigid laterally,

but it may be made rigid in both directions ii requi ed. so

. Preferably i'ormed integral with the crosspiece at'its middle is aflange portion 23 which may be folded over the top of the nose-piece andclamped in fixed relation thereon, as illustratedinl'igure3,oritmaybeiormedintoasnapspring ll to permit it to be easilydetached therefrom as illustrated in Figure 6.

The construction shown in Figure 14 is substantially the same with theexception that two flanges are used to secure the cross-piece to thespring instead of one, and the cross-piece is bowed between the flangedconnections for the purpose heretofore described.

The ends of the metal cross-piece are bent a quarter turn andrectangular shaped slots 24-24 respectively, are formed at apredetermined distance from the ends, the end portions of thecross-piece being bent back upon itself to form springs 25-45respectively, which serve to form pockets 26-26 respectively, in whichthe L shaped ends of the side-clips 21-21 respectively, may rest and becovered by the leafs of the springs,

which also clamp the ends of the clips firmly in position in thepockets.

The side-clips are made wide and stifi enough to clasp the sides of thehead by reason of the spring action of the ends of the cross-piecetogether with the contributing spring action of the side clips whichexert a clasping action since they are not entirely rigid.

In each of the joint constructions shown where the parts are made ofmetal, they are alike in that they are separable; and that the ends ofthe side clips are held by springs formed integral with the cross-piece.

Also it is to be observed that the cross-pieces are connected .to thenose-piece of the glasses only, and preferably extend over the glasses,or above them, thus relieving them of strains caused by attaching theends of the side-clips directly to the outer ends of the glasses, andalso removing the danger of breaking them when drilling holes requiredwhen constructed in that manner.

It will also be understood that it is not necessary that a spring typeof nose-piece should be used; it is only necessary to have the elements28 or their equivalent, to rest on the nose to support the glasses innormal position for vision.

It will also be understood that the ends of the cross-piece may be bentdownward, as illustrated in Figure 15 and that it may be changed in formto suit the various forms of nose-pieces such as now in general use.

Those skilled in the art to which this invention pertains will have nodimculty in understanding" the details of the constructions shown anddel scribed herein, and further description is deemed unnecessary inview of the further details set forth in the claims herewith presented.

Having thus described my invention I claimas new: 10 1. An attachmentfor eye glasses adapted to be rigidly and detachably connected to thenosepiece of a pair of eye glasses, said attachment including across-piece of strip formation having an opening in each end, areturn-bent spring arm at each end oi the cross-piece overlying theadjacent opening, and a side clip for each end of the cross piece havingan angle end removably inserted in the opening with the spring armoverlying the angle end for retaining the side clip in position. 2. Anattachment for eye glasses adapted to be rigidly and detachablyconnected to the nosepiece of a pair of eye glasses, said attachmentineluding a cross-piece of strip formation having an opening in eachend, a return-bent spring arm at each end of the cross-piece overlyingthe adjacent opening, a side clip for each end of the crosspiece havingan angle end removably inserted in the opening with the spring armoverlying the angle end for retaining the side clip in position, and 9.lug on each end of the cross-piece outwardly of the opening formingabutments for the side clips.

3. An attachment for eye glasses adapted to be rigidly and detachablyconnected to the nosepiece 01' a pair of eye glasses, said attachmentincluding a cross-piece of strip formation having an opening in eachend, a return-bent spring arm at each end of the cross-piece overlyingthe adjacent opening, a side clip for each end of the crosspiecehaving-an angle end removably inserted in the opening with the springarm overlying the angle end for retaining the side clip in position, anda complete hinge construction carried by each side clip adjacent itsconnection with' the cross- 45 piece and independent of said connection.
